Go to Advance System section for point count system and other details. All
openings have been broken down to detail % and number of tricks make using
double dummy database of >2 million hands. The
amazing part of the advance system is that 12-14 HCP, 15-17 HCP, 18-19 HCP,
20-21 HCP NT hands are all identified by 1C and a following bid or 1NT or 2NT.
1C bid has no hands in the 15-17 range. The system also handles very precise
weak two openings. Very difficult to defense because of the multi 1C, 2C
and 2D bid. Able to open 2S and 2H with exactly 5 cards and 8-10 HCP as part of
2D opening. Able to open 5 Card 9-10 HCP diamonds, and 8-10 HCP 6 card club and
diamonds as part of 2C opening.

I developed the Cheung's 5 card Minor System in 1995 and was approved for
play by then the head director for district 21. At that time I was competing for
a mini-McKenney title in the NABC Master division. I was and still is fascinated
by different bidding systems. I have most of the bridge books in
print and some old out of print stuff. Here are some of the reasons I developed
the Cheung's 5 card Minor System:-

It was fun to have your own system.

A different system which is unfamiliar to your opponent is a big
advantage. This is especially true in pair games where you only play 2 boards
against each opponent. For a long time I have problem playing against the big
club system until I develop my own defense against it.

I was not good enough to compete against the top players in pair games
which I was forced to play when there is no team games or if I got knock out
of the team game. So I needed some extra tool to do better in the pair games.

I was trying to use a new system to gain strategic advantage over my
opponents. The weakest part of the standard 2/1 system is in the minor
opening. The opening of 1C and 1D does not tell you how long the suit is other
then it is at least 3. (or sometimes people play 1D as at least 4; then 1C
could be 2) I want a system which is similar to the 5 card major system and
can identify 5 card minors easily.
